I had my car protuned in the late summer in CT, but it seems to hit a fake overboost when the temp drops below freezing. My tuner emailed me a lower waste gate map, but I don't know how to install it to my car. Do I load it to my AP from my computer or do I run my laptop through my AP and install that way? Also, do I run this map permenately, or do I swap them based on the seasons?
Thanks, and sorry for the super noob question.
